TH REE-WHEEL RIDING GANG-PLOW.

SPECIFICATION forming part of Letters Patent No. 357,573, dated February15, 1887.

Application filed June 21, 1886.

To all whom it may concern:

Be it known that I, BENJAMIN F. BUTLER,- a citizen of the United States,residing at Davenport, in the county of Scott and State of Iowa, haveinvented new and useful Improvcments in Three-Wheel Riding Gang- Plows,of which the following is a specification.

My invention consists of improvements in the construction andarrangements of the contrivances 0f three-wheel riding gang-plows forenabling two or more plows to be used in the gang; also, for regulatingand controlling the vertical inclination of the points of the plows;also, for regulating and cont-rolling the depth of the furrows by, thecranked axle of the main, wheels, one of which runs in the furrow, andalso for regulating and controlling the position of the tongue and theevener relatively to the plows, all as hereinafter fully described,reference being made to the accompanying drawings, in which Figure 1 isa plan view. of my improved wheel-plow. Fig. 2 is a side elevation ofthe plows and plow-frame and section of the axleadjusting frame onthelinex x of Fig. 1. Fig. 3 is a side elevation of the machine with theaxle sectioned on the line y 3 Fig. 1.

I make a beam-frame consisting of two or more longitudinal parallelbeams, a, according to the number of plows b which I wish to use,together with the requisite cross-timbers c or other stays, d, to whichI attach a plow, b, and colter e, for each beam by suitable stocks orstandards, as commonly done, and I mount said frame on a caster-wheel,f, at the rear and on the lifting-frame at the front, said frameconsisting of (preferably) two arms, g, to each beam pivotally supportedat the middle on the axle h,crosswise thereto, and all connected at thefrontends together by the bar 2', to which and to one of said arms thelifting ratchet-sector j is rigidly attached. Thebeams are pivoted tothe rear ends of these arms at 70, and with the ratchet-sector there isa pawllever, l, and pawl m, pivoted and turning loosely on the axle forshifting the liftingframe, and having anotched holding-rack, n, locatedon one of the beams in suitable proximity to the drivers seat 0, forbeing used conveniently by the driver thereon to shift the lifting-framefor raising and lowering the front Serial No. 205,752. (No model.)

I end of the beanrframe by the lever, and setting it by the rack,according as it maybe desired to adjust the points of the plows asztothe vertical pitch or inclination.

v In this example of my invention I have represented two beams in thebeam-frame for two plows with one set of cross-timbers, c, and stays d,and two sets of arms, 9, in the liftingframe; but if I employ threebeamsthe third beam will be connected as these are by othercross-timbers and stays, two more arms will be employed in thelifting-frame, and the lifter-frame bar 7;, connecting said arms, willbe suitably extended, and the extension, the additional lifting-arms,and the cross-timbers and stays for the additional beam may all bedetachably connected, so as to be attached or disconnected at will, ifdesired. In such case the axle would be extended on the land side toenable the additional plow to be connected on that side, for therelative position of the plow on the other side to the wheel that runsin the furrow must be the same whether two or more plows are used in thegang.

It will be seen that in a gang-plow that is variable as to the number ofplows to be used in the gang it is important to have thetongueand-evener connection so that they may be shifted laterallyaccordingly. It is also desirable to some extent, whether variable ornot as to the number of the plows, for regulating the draft undervarying conditions of soil, depth of the furrows, number of animals inthe team, and for other reasons, for which, and also for a contrivanceto adjust the cranked axle to vary the wheels according as both run onthe land or one in the furrow, I have arranged the axle anddraft-regulating frame, consistingof the arms p, parallel barsq,connecting said arms, and the evener-connecting plate 3, on the axle,pivoting the arms thereto outside of the lifting-frame, and to thisframe I connect the tongue t by a clip, a, fitted to the parallel barsq, so as to shift along them, together with a series of holes, '0, inthe evenerplate for enabling the tongue and evener to be shifted to andbe set together in different positions along said bars, when they may besecured by the clevispin of the evener or by other suitable means forthe draft-regulator, and with this frame I also arrange a lever, '20, onthe axle by the side of one of the arms, and rigidly connected to theaxle, with a stop-latch, m, on it, and a notched sector, y, on the arm,so that by shifting the lever up or down the axle will be turnedaccordingly, and may be secured in any position by engaging the latchwith the sector.

W'ith the caster-wheel I have arranged a shifting-lever, s, which ispivoted near about its middle to the beam-frame and ranges forward to apoint a little in front of the drivers seat, where it terminates in avertical handle, a, for shifting it along a notched stop, I), as may berequired for the guiding of the ma chine. The rear end of this lever maybe connected to the pivot-stock of the caster-wheel in any approved way;but I have in this case employed the forked arm 0 on the pivot-stock,with the end of the lever lodged in the fork.

With these improvements I have provided a riding gang-plow of verysimple and cheap construction, having all the requisite adjustments, andbeing very easy and convenient to operate,-and by the simplicity of theconstruction being adapted for durable service.

Vhat I claim, and desire to secure by Letters Patent, is-

1. The combination, in a riding-plow, of the beam-frame consisting oftwo or more beams, a, each having a plow, b, and being connected bysuitable cross-timbers and stays, the casterwheel carrying the rear endof the beam-frame, the cranked axle, the lifting-frame pivoted on theaxle and having the front end of the beamframe pivoted to its rear end,and the pawl-lever and pawl adapted for the turning of the lifting-frameon the axle for the raising and lowering of the beam-frame, saidbeam-frame being pivoted to the lifting-frame, substantially asdescribed.

2. The combination, with the beam-frame and cranked axle having onecrank only, of the lifting'frame consisting of the cross-arms g, pivotedon the axle, and lifter-bar t, conmeeting said arms and having theratchet-sector j, attached to one of said arms, together with thepawl-lever pivoted on the axle, the pawl, and the holding-rack for thelever, substantially as described.

- 3. The combination, with the cranked axle having one crank only,beam-frame, and plows, of the draft-frame consisting of arms 1),parallel bars q, evener-plate s, and the adjustablyconnected tongue-clipu, said evener-plate having a series of holes for the adjustment of theevener, substantially as described.

4. The combination, with the cranked axle having one crank only,beam-frame, and lifterframe pivoted on and connecting the beamframe tothe axle, of the draft-frame having the axle fitted to turn in it andprovided with the notched sector, the crank-shifting lever rigidlyattached to the axle, and thestop-latch of the lever, substantially asdescribed.

5.- The tongue pivoted to the clip a, fitted adjustably along thedraft-frame, in combina tion with the evener-plate, also attached tosaid draft-frame and adapted for shifting the evener along it with thetongue, substantially as described.

In witness whereof I have hereunto signed my name, this 22d day of May,1886, in pres ence of two witnesses.

BENJAMIN F. BUTLER.
